SYRINGE.

SPECIFICATION forming part ot Letters Patent No. 634,108, dated October 3, 1899.

pnlication led August 20, 1898. Serial No. 689,075. .(No model-D fo @ZZ wtont t muy concern:

Be it known that I, ANDREW L. HENRY, a citizen of the United States, residing at Ladoga, -in thecounty of Montgomery and State 'of Indiana, have invented certain new and useful Improvements in Syringes, of which the following is a specification.

Y This invention relates more especially to the nozzles or discharging portions of syringes;

ro and it principally consists in making such nozzles of small meta-l tubes bent ata central point with the two sides arranged in a substantially parallel relation, the discharge-oriices being near the bend on the inner or adjacent sides of the tube portions.

Referringto the accompanying drawings, which are made a part hereof and on whichA similar letters of reference indicate similar parts, Figure l is a top or pian view of asyrzo inge embodying my said invention; Fig. 2, a

side elevation of the same; Fig. 3, a horizontal sectional view, on an enlarged'scale, of

the nozzle portion, the central part thereof being broken away 3 and Fig. 4, a detail sectional view on the dotted line 4 4 in Fig. 3,

but on a still further enlarged scale.

" In said drawings the portions marked Arepresent the cylinder of an ordinary syringe, B

the piston thereto, and C the nozzle embodying myrpresent invention.

The present invention relates solely to theY nozzle portion, and the cylinder A and piston B are shown merely to illustrate acomplete structure, and I desire it to be expressly understood that any other syringe structure or body capable of supplying a fluid to the nozzle may be employed without departing from my invention.

The nozzle C, as hereinbefore stated, is

' 4o composed of a tube of suitable size andinato a suitable union-piecelO', said union-piece being attached in a similar manner as other Vfrom the center outwardly.V

nozzles are (or in any desired manner) to the duid-supplying portion or body of the syringe. Near the extremepoint in the adjacent sides or facing portions of the tribe are perforations c, which are preferably arranged exactly opposite each other. This arrangement insures that the streams shall operate upon each other to create a tine spray, which is lthus discharged laterally in substantially all directions from thepoint of the nozzle.

The-space between the two tubes forms a passage-way for the outflow of the fluid. The perforations being thus arranged between the tubes are protected from contact with the parts while the instrument is being inserted `and withdrawn, and are thus free .from the danger ot gathering diseased matter orbecoming'clogged thereby.

Among the other uses to whichA my syringe is especially adapted is the insertion and saturation of absorbent material within the parts to be treated. ln doing this work the absorbent material is placed upon the point of the syringe-nozzle in such quantity and form as may be desired, and the syringe having previously been charged with the desired saturating liquid or medicament the material is forced into place by the point of the nozzle,

andsaid liquid is afterward dischargedinto the said absorbent material, saturating it- Strong medicaments -may thus'be applied directly to the diseased parts, where desired, without previously coming in contact with any ofthe parts which must be passed in reaching such diseased parts. The discharge of fluid being lateral and being prevented by the form of the nozzle from passing beyond the end of said nozzle, all danger of forcing the liquid beyond the point desired is obviated.

'A The tine hollow tubes of which the nozzle lis composed are flexible in a highl degree and may be bent'in almost any form desired, so that the course and direction maybe adjusted from time to time as'the exigencies of any case may require, while obviously the nozzles may be made of widely-varying lengths, so

as to penetrate to any desired depth. A physician having a syringe with a set of these nozzles of varyin g sizes and'lengths is enabled to conveniently do much work which has heretofore been regarded as very diicult.
